This illustration depicts the plumbing layout under a kitchen sink, including an air-admittance valve (AAV). The AAV is installed on the drainpipe to allow air into the system, preventing siphoning and ensuring proper drainage without the need for an external vent stack. The diagram also shows a P-trap, which prevents sewer gases from entering the home by maintaining a water seal. Flexible water supply lines connect the faucet to the hot and cold water shut-off valves. A garbage disposal is attached beneath one sink, and the drain system efficiently directs wastewater to the main drainage line. The setup combines functionality and space optimization for a clean and efficient kitchen plumbing system.
